An acoustic neuroma is a noncancerous growth that develops on the eighth cranial nerve. Also known as the vestibulocochlear nerve, it connects the inner ear with the brain and has two different parts. One part is involved in transmitting sound; the other helps send balance information from the inner ear to the brain.Acoustic neuromas -- sometimes called vestibular schwannomas or neurolemmomas -- usually grow slowly over a period of years.F2 is an inherited disorder characterized by the growth of noncancerous tumors in the nervous system. Acoustic neuromas are the most common of these tumors and often occur in both ears by age 30. NF2 is a rare disorder. It accounts for only 5% of acoustic neuromas.
